FIELD OF THE INVENTION

The present invention provides a faucet, more particularly to faucet outlet structure having two hollow ducts fluidly connected with each other.

BACKGROUND OF THE INVENTION

Generally, adding lead in copper materials would facilitate manufacturing and casting process, so it is widely used for manufacturing faucet structure. However, in recent years, since the price of copper continues to rise and the addition of lead is strictly regulated by law, the processing and material costs of faucets continue to increase. Therefore, the faucet manufacturers gradually shift to use zinc alloy as an alternative material, which is cheaper and easy for surface processing to achieve cost saving in raw materials and processing. However, zinc alloy becomes easy to peel after exposing to water due to oxidation.

So, in most faucet structure, a plastic inner tube is disposed to avoid zinc alloy from directly contacting with water to cause oxidation. But, because conventional water outlet duct of the plastic tube has an angle of double concave, it is difficult for the process of injection molding, as well as assembling the structure of the outlet pipe at the faucet, which may reduce the production rate of the faucet.

Please refer to U.S. Pat. No. 8,439,077 (hereafter '077), which a faucet outlet structure is disclosed. The faucet outlet structure includes a faucet base, an outlet pipe and two outlet ducts. The outlet pipe is made by zinc alloy using die-casting processing method to form in one piece, and the two outlet ducts are made by plastics and engaged with each other. Each engaging portion has a connecting portion, wherein a protruding edge of the first connecting portion of the first outlet duct has a through restricting hole, and a through slot is diagonally and recessedly formed at the opening of two protruding edges and the through slot and the restricting hole are connected perpendicularly. The second connecting portion has a block protrudingly on both sides and the block is engaged with the restricting hole of the first outlet duct. According to the abovementioned structure, two outlet ducts penetrate through both sides of the outlet pipe, align to engage and then turn, so the two outlet ducts can be fast, easily and securely positioned at the bended outlet pipe.

However, one end of the second outlet duct is connected to the first outlet duct, and the other end of the second outlet duct is against the water outlet channel with the positioning ribs and the supporting edge. Therefore, the structure is complicated and hard to disassemble.

SUMMARY OF THE INVENTION

An objective of this invention is providing a faucet outlet structure, which is convenient to assemble and disassemble and further to replace elements because the first connecting portion of the first hollow duct and the second connecting portion of the second hollow duct are connected with each other and the first embedding portion and the second embedding portion are detachably concave-convex matching.

To achieve above objectives, a faucet outlet structure is disclosed and comprises: an outlet tube, being an L-shaped hollow structure and having an inlet section, an outlet section, and a bending section disposed between the inlet section and the outlet section, two ends of the bending section are respectively fluidly connected with the inlet section and the outlet section, and a first embedding portion is arranged inside the bending section; a first hollow duct, accommodated in the outlet section of the outlet tube and having a pipe portion, a second embedding portion, and a first connecting portion, the pipe portion is accommodated in the outlet section of the outlet tube, the second embedding portion is connected onto the pipe portion and detachably connected with the first embedding portion, and the first connecting portion is connected onto the pipe portion and arranged toward the inlet section of the outlet tube; and a second hollow duct, accommodated in the inlet section of the outlet tube and having a second connecting portion, the second connecting portion is fluidly connected with the first connecting portion of the first hollow duct.

In some embodiments, a sealing ring is sleeved between the first connecting portion and the second connecting portion.

In some embodiments, the first embedding portion and the second embedding portion are concave-convex matching.

Further features and advantages of the present invention will become apparent to those of skill in the art in view of the detailed description of preferred embodiments which follows, when considered together with the attached drawings and claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings where like characteristics and features among the various figures are denoted by like reference characters.

FIG. 1 is an exploded view of a faucet outlet structure according to present invention. FIG. 2 is a cross section view of the faucet outlet structure according to present invention. FIG. 3 is a perspective view of the faucet outlet structure according to present invention. FIG. 4 is an outside view of the faucet outlet structure according to present invention.

Please refer to FIG. 1 to FIG. 4, the faucet outlet structure 100 may comprise an outlet tube 1, a first hollow duct 2, and a second hollow duct 3.

The outlet tube 1 may be substantially an L-shaped hollow structure and have an inlet section 11, an outlet section 12, and a bending section 13 disposed between the inlet section 11 and the outlet section 12. Two ends of the bending section 13 may be respectively fluidly connected with the inlet section 11 and the outlet section 12. And a first embedding portion 14 may be arranged inside the bending section 13.

The first hollow duct 2 may be accommodated in the outlet section 12 of the outlet tube 1 and have a pipe portion 21, a second embedding portion 22, and a first connecting portion 23. The pipe portion 21 may be accommodated in the outlet section 12 of the outlet tube 1. The second embedding portion 22 may be connected onto the pipe portion 21 and detachably connected with the first embedding portion 14. And the first connecting portion 23 may be connected onto the pipe portion 21 and arranged toward the inlet section 11 of the outlet tube 1.

Preferably, the first embedding portion 14 and the second embedding portion 22 may be concave-convex matching. That is, the first embedding portion 14 may be a concave structure and the second embedding portion 22 may be a convex structure (shown as in FIG. 1), or the first embedding portion 14 may be a convex structure and the second embedding portion 22 may be a concave structure (not shown), but not limited thereto.

The second hollow duct 3 may be accommodated in the inlet section 11 of the outlet tube 1 and have a second connecting portion 31. The second connecting portion 31 may be fluidly connected with the first connecting portion 23 of the first hollow duct 2. Preferably, a sealing ring 3 (such as an O-ring) may be sleeved between the first connecting portion 23 and the second connecting portion 31.

Therefore, it is convenient to assemble and disassemble and further to replace elements because the first connecting portion 23 of the first hollow duct 2 and the second connecting portion 31 of the second hollow duct 3 are connected with each other and the first embedding portion 14 and the second embedding portion 22 are detachably concave-convex matching.
